VWAQON-RAISER.

SPECIFICATION forming part of Letters Patent No. 490,787, dated January31, 1893-\ Application filed July 16 1892. Serial No. 440,194. (Nomodel.)

To all whom it may concern.-

Be it known that I, CLARENCE (IHALLMAN, a citizen of theUnited States,residing at Pauls Valley, in the Chickasaw Nation and Indian Territory,have invented certain new and useful Improvements in Wagon-Raisers; andI do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same. The special objectof the invention is to combine pulleys, ropes and levers so as to hoistwagonbeds by handpower with ease and convenience.

The invention will first be described in connection with the drawingsand then pointed out in the claim.

Figure 1 of the drawings is a side elevation of the whole apparatus,Fig. 2 an end-elevation thereof and Fig. 3 a horizontal section.

In the drawings, A represents the frame which supports the pulleys andlevers, and which consists of the'two horizontal and parallel base beamsa a, the four vertical corner posts a mortised therein and also in twohorizontal upper beams a 0. represent three horizontal pulley-beams letinto and fastened on the beams a B B are two wagonbed supports of whichone end is connected by a rope C with the equal-armed lever D near itsmiddle, each rope passing over two diagonally arranged pulleys E F whileeach of the ropes C connects the other end of the supports B with theouter ends of the lever D, after passing over the aligned pulleys G G.All the pulleys turn on pivots in the hangers Hwhich are suspended fromthe beams a. The leverD is fulcrumed at the middle on a power lever Kpivoted, near one end, at 70, on a vertical post a and provided with ahandle 10'. It will thus be seen that the weight'of the wagon isbalanced by an equalizing lever D Whose fulcrum is the point of strainfor the actuating lever K. When the lever K has had its handle ispressed far enough down to raise the wagonbed to the elevation desired,it is held in a catch I on the post a.

What I claim as newand desire to protect by Letters Patent is:

In a wagon raiser, the combination of the frame A carrying on its upperhorizontal beams, hanging pulleys E F and G G, the

wagon-supports B B and middle-pivoted lever D connected by ropes asshown, and the lever K carrying the fulcrum of lever D, allsubstantially as described and for the purpose setforth.

In testimony whereof I have affixed my signature in presence of twowitnesses.

CLARENCE C. HALLMAN.
